In my 94 FSM and Riley's 95 FSM there are 3 vacuum test diagnostic procedures for the EGR system. The last two direct you to connect lines to the intake manifold. WTF?? Is there a vacant vacuum port on the intake manifold I don't know about? Looked but can't see anything.
The manuals also make it fairly unclear where to apply and/or measure the vacuum except for the first test. I think in the second test the vacuum gauge stays in the same place as this first, but in the third test I am not sure.
If anyone speaks toyota mechanicese and can explain the last two tests in layperson's terms I will be in your eternal debt.
thanks
